Neutrino astrophysics with the ANTARES Cherenkov Detector

The ANTARES neutrino telescope is currently the largest water Cherenkov detector in operation in the Northern Hemisphere. The detector is a lattice of 885 Optical Modules distributed over 12 lines, located 40 km off the Southern French coast at a depth of about 2500 m. Its main scientific goal is the detection of high energy cosmic neutrinos from galactic and extra galactic sources using the Cherenkov photons emitted along the pattern of neutrino-induced charged leptons. The detector has been taking data regularly since 2006 in a partial configuration and has been completed in Spring 2008. The status of the experiment is reported and a selection of the latest results is discussed. In particular, this paper presents the up to date upper limits for diffuse high-energy cosmic neutrino flux, the searches for point sources, the multi-messenger analyses and the measurement of the neutrino oscillations
